\M PTROVEMENTI IN PAPER- BAGS.

Specification forming part of Letters Patent No. 221,144, dated November 4, 1879; application filed I August 5, 1879.

fl" 0 all whom it may concern;

Be it known that I, DANIEL APPEL, of

Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Paper Bags; and I do hereby declare the following to be a. full, clear, and exact description of the invention,

, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

, My invention relates to paper bag. and it consists, first, in the bag-pattern, and, sec-.

ond, in the manner of folding said pattern, as hereinafter specified and claimed.

In the drawings, Figure 1 is a developedtube and the style of its lateral folds or pli-' cations. Fi 3 shows the manner of applying the paste to the tube, the paste being shown' in cross-lines. 'Fig. 31; is an end view in cross section of the tube. Fig. 4 shows the first fold in forming the bag-bottom. Fig. 4:} is an end view of the tube as shown in Fig. 4. Fig. 5 illustrates the second fold; Fig. .55}, an end view of the tube as folded in Fi 5; Fig. as, a plan view of said fold Fi 6, a view ofthe completed bag as folded for packing; Fig. 7, a bottom view of the bag as opened and in use.

To form the bag shown in the drawings, the paper is preferably received in-the form of a flat sheet from a continuous roll, and it is bent andfolded into the form of a tube with plieated sides, such as shown in Figs.'-2 and 21; of the drawings. This tube is to be cut oti' into suitable lengths, as illustrated in Fig. 2, and when thus cut it is to be pasted and folded in the manner that- I will shortly proceed to specify.

It will be observed that the end of the pattern A (shown in Fig. 1) has its central por-, tion provided with a rectangular projection, B, and its two side portions providedwith rcctangulz'lr recesses A, said sheet end having plane portions, B, formed, respectively, be tween said projection and recesses.

When the pattern is folded into the plicated tubular form, as shown in Figs. 2 and 3, this formation of the pattern presents the surfaces AB for the reception of paste, which is applied iu the manner indicated by the crosslines in Fig. 3.

After the paste has been applied the first. fold, as shown in Fig. 4, is made, and this fold consists in turning the lower corners of the body upon the face of the bag, as indi cated.

The second step consists in opening or partially unfolding the. side plications substantially in the manner shown in Figs. o, 5g, and

5%, and in wiping the folds C 0 between the side plications, in the manner illustrated by the figures of drawings just above named.

The folds, it will be noticed, include a'portionof each end of the lipB. This will leave exposed upon the seam-face of the bag the turned corners D I) of the upper pli'cations, D D.

After the folds and'armngement of folds shown in Figs. 5, 5%, and havebeen made, the bag is completed by simple pressure be tween rolls or otherwise, and this pressure results in the product shown in Fig. 6 of the drawings.

A bag thus made will not only be thoroughly pasted and perfectly tight, but when opened it presents a square bottom, as show in Fig. 7.

What I claim is- 1. The pattern-sheet A, whose end has its central portion provided with the projection ,B, and its, two side portions provided with the rectangular recesses A, said sheet end having plane portions B, formed, respect ively, between the projection and the recesses. substantially as set forth.

2. The process of making a paper bag, eonsisting of the following steps: 'iirst, forming a tubular blank with an internal fold along each edge; second, folding the two triangular corners of one of said folds over onto the tubular body; third, opening out the two inernal edge folds; fourth, tucking in the trh angular folds of the other internal fold and forming the end lap; fifth, flattening the folds thus formed, and completing the bag by subjecting the blank to pressure. substantially as set forth.

In testimony whereof I have signed my name to this specification in the pfesenee of two subscribing witnesses.
